macOS packages now include completion files for elvish and fish shells (#221, @TymekDev).

rig available --list-distros output now includes PPM support, whether the a distro is retired, the EOL and in the JSON format also the last R version for that distro.

rig add is now better at detecting PPM support for new Linux distribution versions. In particular, new Linux distribution releases do not need a rig update to learn about PPM support. Relatedly, rig system detect-platform now does not report PPM support. Use rig available --list-distros to see which Linux distributions have PPM binaries.

rig run now exits with the exit code of the R process (#261).

Custom certificates via the SSL_CERT_FILE environment variable work again (#227).

rig library default does not crash now (#240).

rig now uses a better way to get the user's home directory, that works on systems without an /etc/passwd database (#228).

Windows: rig supports Rtools45 now.
